Summary

Did you know?

The Karner blue butterfly (Lycaeides melissa samuelisis) is an endangered species and its caterpillars feed only on the leaves of wild lupine (Lupinus perennis ssp. perennis) which is sometimes found in successional northern sandplain grasslands in eastern New York (e.g., Albany Pine Bush and Wilton Wildlife Preserve and Park).

State Ranking Justification

This community is widespread throughout New York State, where the substrate is sand. There are an estimated 500 to 2,000 extant occurrences statewide and there are only a few good quality examples in New York. Successional northern sandplain grasslands are threatened by fire suppression, invasive species, and fragmenting development.

Short-term Trends

The number and acreage of successional northern sandplain grasslands in New York have probably declined slightly in recent decades due to fire suppression, disturbance by off-road vehicles, trash dumping, and development.

Long-term Trends

The number and acreage of successional northern sandplain grasslands in New York have probably had very large declines from historical numbers due to fire suppression, fragmentation, disturbance by off-road vehicles, trash dumping, and development.

Conservation and Management

Threats

As a fire-dependent natural community, the primary threat to successional northern sandplain grasslands is the suppression of fire. Lack of fire will likely result in the invasion of woody species from the surrounding woodlands that may convert the grasslands to shrublands and eventually to successional hardwoods. Other threats to this community include fragmenting development (e.g., residential, agricultural, commercial, roads, utility ROWs) and recreational overuse (e.g., ATV use, off-trail trampling, trash dumping). Nearly all examples of successional northern sandplain grasslands are threatened by invasive species: including invasive woody plants, such as black locust (Robinia pseudoacacia), shrubby honeysuckles (Lonicera tatarica, L. morrowii), and multiflora rose (Rosa multiflora), and garlic mustard (Alliara petiolata); and invasive herbaceous plants, such as spotted knapweed (Centaurea stoebe. ssp. micranthos), cypress spurge (Euphorbia cyparissias), and bird's-foot trefoil (Lotus corniculatus).

Conservation Strategies and Management Practices

Develop and implement prescribed burn plans at appropriate sites. Reduce or minimize fragmenting features, such as residential and commercial development, roads, abandoned clearings, unnecessary trails, etc. Restrict mountain bikes and ATVs to designated trails and least sensitive areas, and prevent dumping of trash. Remove or control invasive species where appropriate.

Development and Mitigation Considerations

This community is best protected as part of a pine barrens ecosystem, encompassing patches grasslands, scrub oak shrublands, and pitch pine-oak forests. Development should avoid fragmentation of such systems to allow for nutrient flow, seed dispersal, and seasonal animal migrations within them. Bisecting trails, roads, and developments can also allow exotic plant and animal species to invade.

Inventory Needs

Survey for occurrences statewide to advance documentation and classification of successional northern sandplain grassland. Continue searching for large sites in good condition (A- to AB-ranked).

Research Needs

Determine the optimal fire regime for this community.

Range

New York State Distribution

This community is widespread throughout New York State, where the substrate is sand, but somehat restricted to sites where the substrate is moist sand and kept open through prescribed burning or infrequent mowing. It is probably represented by different regional variants. It is typically a small patch community with very few large patch occurrences known from the Great Lakes Plains.

Global Distribution

This broadly-defined community may be widespread at northern latitudes where the substrate is sand. Examples with the greatest biotic affinities to New York occurrences are suspected to span north to southern Canada, west to Minnesota, southwest to Indiana and Tennessee, southeast to Georgia, and northeast to Nova Scotia.

Identification Comments

General Description

A meadow community that occurs on open sandplains that have been cleared and plowed (for farming or development), and then abandoned. This community is usually dominated by a low, dry turf of sedges and grasses less than 30 cm (12 inches) tall, and includes patches of open sand and patches of soil covered with mosses and lichens.

Characters Most Useful for Identification

These grasslands are dominated grasses and sedges, such as little bluestem (Schizachyrium scoparium), hairgrass (Avenella flexuosa), Pennsylvania sedge (Carex pensylvanica), common poverty grass (Danthonia spicata), panicgrasses (Dichanthelium acuminatum ssp. columbianum, D. linearifolium, D. depauperatum), and other sedges (Carex rugosperma, C. lucorum). Characteristic herbs with low percent cover include bracken fern (Pteridium aquilinum var. latiusculum), stiff leaf aster (Ionactis linariifolius), butterflyweed (Asclepias tuberosa), round-head bushclover (Lespedeza capitata), whorled loosestrife (Lysimachia quadrifolia), and pale bluets (Houstonia longifolia).

Elevation Range

Known examples of this community have been found at elevations between 250 feet and 1,740 feet.

Best Time to See

Late summer (August-September) is an excellent time of year to see little bluestem (Schizachyrium scoparium) blowing in the breeze.
